A little birdie told me one early morning that Santa will be bringing the liberated v1.20 to all of 1000X loyal fans 

Thank you Santa!  :-+

It is only for the older WinCE based models, correct?

It is. The Linux ones to me should be called 1200x.

But...wait ! There is more !    :D

It comes with 2 Megapoints of memory , double of what was achieved until now   :box:

It is standard 2Mpts on the 1200X series, so maybe it is something they released with 1.20 on the old 1000X scopes?

Nope, just retested on a v1.20 with no mem hack, returns 1Mpts:



Edit: both screenshots are with memMax license enabled by the way.
Edit: Keysight's Release Note on v1.20 did not mentioned memory change either.

Edit3: Santa said he's done many more memory tests than one may think  >:D , interesting details will come in a separate post.

Ok,

so... maybe I am off but wanna ask someone who did the HW and FW mod on the edux scope how the square wave (demo 1khz) looks like on the X1 probes.
Mine has a skew on the horizontal section of the waveform especially if you zoom in on vertical but noticeable from 1v(both ch1 and ch2 are the same).
I just want to know if this is a mod issue(like the output from the diff amp) or something else.
On x10 probes I can get rid of that skew by adjusting the probe trimmers.
And if the HW mod is different than stock edux.

Thanks guys.

You do not need wavegen to compensate probes, just connect the probes to the exposed terminals on the Edux. Turn off Training signals and the scope will output the regular probe compensation square wave. The mod did not affect that  circuit.

No, compensation 1khz works ok... but it looks like in attached picture on x1 probes...

Just adjust the compensation control on the probe. This is why probes have them.

Yeah well, I know that :) But the compensation is only on 10:1. My question was is it normal for the wave to look like that on X1 probes?

Probes have more input capacitance on x1, so it makes sense a same square wave would look "slopier".

Thanks,
I know the difference, but I just did not remembered it like this before update!
Well maybe i am seeing things.

At 1kHz?

No it is not normal (DSOX1102G, N2140A 200MHz probes, x1).

Thank man,

So I was not crazy :)

Now.. the only thing that comes to my head is that the filter parts after the diff amp are not exactly right. Or maybe I am wrong?
Someone with more experience could shine some light.

I've done the mod exactly as showed on this thread.

Thanks.

Have you done the mods as pointed by rbaleiro (page 28)?

Have your unit passed self-calibrarion ?

Hi,

Yes, did the mods exactly (and checked on back pages for confirmation)
All the self calibrations passed (HW and USER)

Mine is the EDUX10002A version and I have done the CH1 CH2 and TRIGG(and extra resistors for ext in) mods plus 23 ID for DSO1102A.
Everything works fine except that weird thing on X1 probes. I feel that it might be related to the filter on the diff amp. I've used 47uh and 4.7 pF as others said or maybe when you do the mod the trimmer on the input has to be readjusted? I am not an expert on how the oscilloscope front end works.

Thanks for the time.

They look the same, your picture and the other one that says yours is not normal.  Have you measured rise time to have a more specific value rather than an image?
